Question

Two small balls A and B are projected in same
vertical plane simultaneously with same speed
of 20m/s at t=0. Ball A has an initial horizontal
velocity and B has initial velocity at an angle o
above the line joining A and B as shown. If the
projectiles collide in mid air at time t, then :

Answer 1

Answer:

can you type your question a bit properly it is confusing me

Answer 2

Two small balls A and B are launched in the same vertical plane simultaneously, with same speed 20 m/s att = 0. Ball A has initial horizontal velocity and B has initial velocity at an angle 0 above the time joining A and B as shown. If the projectiles collide in mid air at time t, then 20 m/s 100 m 20 m/s 100.3 m.
